Abstract
Purpose
The purpose of this paper is to present a heuristic model to better understand the inherently paradoxical and concomitant positive and negative organizational outcomes associated with demographic diversity and value congruence in organizations. It further illustrates the resultant organizational dynamics that result from shifting levels of diversity and value congruence.
Design/methodology/approach
This paper adopts the supply and demand heuristic from the economics discipline and further develops the diversity and similarity curves (DSC) model proposed by Ofori-Dankwa and Julian. Further, this analysis is carried out from both short-run (static) and long-run (dynamic) perspectives.
Findings
This study illustrates how different levels of organizational diversity and value congruence (reflected by diversity and similarity curves respectively) could concurrently result in both positive and negative levels of organizational creativity and competitiveness.
Research limitations/implications
As a heuristic, this study's model is a simplistic representation of the inherently complex set of relationships and outcomes that are associated with paradox in a social setting.
Practical implications
This model has managerial utility for explaining how different levels of diversity in an organizational setting could potentially have different positive and negative outcomes.
Originality/value
This study unpacks the implications of different levels of diversity in an organizational setting and sheds original light on the dynamic nature of virtuous and vicious organizational cycles associated with diversity.

Abstract
Purpose
Microenterprises in emerging economies are known to operate in turbulent and resource-scarce environments. We test our hypothesis that a more comprehensive “Integrated Capital-Based Model” (ICBM) is needed when explaining the performance of microenterprises in such an environment. The model combines traditionally researched financial, human and social capital with more recently emphasized psychological and cognitive capital, providing greater explanatory power than models using only the traditional types of capital.
Design/methodology/approach
We use a pooled linear regression to analyze an existing survey of more than 900 independent business owners who were interviewed seven times between 2008 and 2012 in the Accra and Tema marketplaces in Ghana. We measure the performance of microenterprises using three dependent variables (revenue, profits, and productivity). We contrast the explanatory power of ICBM models against the more traditional models.
Findings
The ICBM has significantly higher levels of explanatory power over the traditional models in examining the performance of these microenterprises. These results highlight the importance of psychological and cognitive capital in emerging economies.
Research limitations/implications
We advocate for a more comprehensive view of capital as shown in our ICBM. However, the data were gathered only in an urban setting, which limits the generalizability to rural parts of emerging economies.
Practical implications
These findings suggest the utility of government and appropriate agencies finding ways to enhance the level of psychological and cognitive capital of microenterprise owners.
Originality/value
This paper's originality stems from hypothesizing and empirically confirming the higher predictive efficacy of ICBM against more traditionally researched capital sources.

Abstract
Purpose
Building on the upper echelons theory and sustainability orientation (SO) literature, this paper aims to examine the possibility that the relationship between chief executive officers’ (CEOs’) SO and venture growth might be mediated by levels of corporate social responsibility (CSR) implementation.
Design/methodology/approach
The authors used data obtained from 211 new ventures operating in Ghana. Multiple regression analysis was used to test the hypotheses.
Findings
The authors found that CSR implementation mediates the relationship between SO and venture growth. In addition, the authors found that, at higher levels of financial slack, the effect of SO on CSR implementation is attenuated. However, the results show that, at higher levels of CEO power, the influence of SO on CSR implementation is amplified.
Originality/value
To the best of the authors’ knowledge, this study is among the first to examine the mediating role of CSR implementation in the relationship between SO and venture growth and also examines two internal contingency factors (i.e. CEO power and financial slack) on this association.

Abstract
Purpose
The Truncated Levy Flight (TLF) model has been successfully used to model the return distribution of stock markets in developed economies and a few developing economies such as India. Our primary purpose is to use the TLF to model the S&P 500 and the firms operating in the Ghana Stock Exchange (GSE).
Methodology
We assess the predictive efficacy of the TLF model by comparing a simulation of the Standard and Poor's 500 (S&P 500) index and that of firms in the stock market in Ghana, using data from the same time period (June 2007–September 2013).
Finding
We find that the Levy models relatively accurately models the return distributions of the S&P 500 but does not accurately model the return distributions of firms in the Ghana stock market.
Limitations/implications
A major limitation is that we examined stock market data only from Ghana, while there are over 29 other African stock markets. We suggest that doctoral students and faculty can compare these stock markets either on the basis of age or the number of firms listed. For example, the oldest stock market was set up in 1883 in Egypt, while the more recent ones were set up in 2012 in the Seychelles and in Somalia.
Practical implications
Scholarly inquiry about the stock markets in Africa represents a rich area of research that we will encourage doctoral students and faculty to go into.
Originality/value
There has been little research done regarding the TLF model and African stock markets and this research has much utility and high level of originality.

Abstract
Purpose
There is an established link between national cultural differences and documented variations in technological innovations across countries. To move beyond a narrow emphasis on national cultures, scholars have suggested using within‐country diversity to compensate for known limitations in national culture measures. Given that ethno‐linguistic diversity is a known source of cultural variation, this paper specifically aims to explore the relationship between culture, ethno‐linguistic diversity and national innovativeness.
Design/methodology/approach
The researchers used publicly available data on patents and trademarks in a multivariate regression context to study the effects of national culture and within‐country diversity on national levels of innovativeness.
Findings
The research found that culture and ethno‐linguistic diversity are independently positively associated with national innovation. More importantly, cultural and intra‐cultural variation measures when taken together account for significantly greater variance in levels of national innovation than does national culture when measured separately.
Research limitations/implications
While this study points to the importance of ethno‐linguistic diversity in explaining national levels of innovativeness, there are other measures of within‐country diversity to be explored.
Practical implications
If national culture were the sole factor in innovativeness, then companies would be limited by their host cultural legacies; since within‐country diversity is also associated with innovation, it provides entrepreneurs, government policy makers and executives with important options for increasing innovativeness.
Originality/value
While previous studies pointed to the potential link between ethno‐linguistic diversity and innovation, prior research has generally not taken this variable into account.

Abstract
Purpose
The purpose of this paper is to examine the historical trajectory of African management research and managerial thinking.
Design/methodology/approach
This paper draws from a review and synthesis of the literature from 1960
-
2012.
Findings
The analysis led to the identification of three distinct phases which reflect the difficult and uncertain beginning of a promising future. The historical pathway model also accounts for the evolution of management philosophies and thoughts and the current state of knowledge.
Originality/value
Although there is a burgeoning stream of African management research, a lack of comprehensive review and synthesis has obscured the enormous strides made. This paper advances a “novel” approach towards theory application and theory creation, building on the “convergence hypothesis” and “divergence hypothesis”. This analysis yielded a number of promising avenues for future research.

Abstract
Purpose
This paper identifies the development of and gaps in knowledge in various management disciplines, including international marketing in relation to political ties in emerging markets, based on a systematic review of the related literature. The paper develops a synthesized integrative framework and provides a research agenda and pathways for future research.
Design/methodology/approach
The study adopts the systematic literature review protocol to investigate the ways in which political ties have been examined in the management literature in various disciplines, such as international business, marketing, entrepreneurship, strategy, innovation, and organization. In total, 114 articles published in peer-reviewed journals from 2000 to 2022 were analyzed.
Findings
The authors believe that studying the impact of political ties on firm outcomes is timely and important as interest in this area of research is growing rapidly. The review reveals that the diverse conceptual and methodological approaches adopted in different management disciplines have resulted in inconclusive and mixed findings on the relationship between political ties and performance.
Originality/value
This is one of the few systematic literature reviews of political ties and firm performance in emerging markets. The authors clarify some of the ambiguities around the subject and offer a path forward for developing current understanding and insights. The study also highlights the major perspectives in management and clarify the similarities and differences in the conceptualization of political ties. In addition, the authors develop an integrative framework of the political ties–performance link in emerging markets.

Abstract
Purpose
The purpose of this paper is to investigate the contingency effects that contextual factors of a networked service environment have on the phased Lean Six Sigma (LSS) implementation frameworks.
Design/methodology/approach
This paper employs the critical realism (CR) case study research methodology to examine the contingent and causal relationships between contextual configurations of business networks, the DMAIC or PDCA phases in an LSS implementation agenda, and business management functions. The authors conducted a single case study on the basis of challenges they met in kicking off lean transportation in the Port of Houston.
Findings
The key finding from the study is a mid-range theory regarding the contingency effects of contextual factors of service business networks on the phased LSS implementation frameworks. The authors found that when there are complexity and dynamics of contextual factors at the field layer, management should focus more on tasks in early LSS phases to emphasize influencing. When there is no centralized authority in the network and the value-system is loosely coupled, management needs to execute more tasks as described in the define, measure and analyze phases with the purpose of both influencing and orchestrating. When individual actors have goals not aligned well with the goal of the business network and have unmatched operations capabilities, these factors should be considered as early as possible in these LSS phases. When a business network has complicated business processes with high unpredictability and uncertainty and individual actors’ value-creation systems are not well embedded in the entire value-creation system, PDCA will be the preferred core structure of an LSS implementation agenda.
Research limitations/implications
This study contributes to the LSS research stream by introducing a causal/contingency model that prescribes the contingency effects of three contextual configurations on LSS implementation. It also contributes to the emerging discipline, business network management, regarding how to use LSS frameworks in strategic planning. It also contributes to the CR school of problem-driven case study by using a strategic initiative framework as a platform and each phase in the framework as a unit. This conceptualization of the entity of interest helps explore the interactions among three theoretical constructs: contextual configurations, phased LSS implementation agenda and management functions.
Practical implications
Managerial implications of this study are twofold. One is the procedure of analyzing the impacts of contextual factors on the causal relationships between LSS implementation phases and network management functions. The entire procedure represents the agenda-setting process of LSS implementation, the most daunting and challenging managerial task in LSS projects. Another one is the guideline on how to determine whether DMAIC or PDCA is appropriate for the LSS agenda when used in a networked environment.
Originality/value
This paper would serve as an excellent resource for both academicians and LSS practitioners in initiating, orchestrating and managing an LSS project in a networked service environment. This study represents the first effort to explore the impact of contextual factors of business networks on lean transformation.
